Service registration

Spec​

do.ListProvidedServices[T any](do.Injector) []do.EdgeService
do.ListInvokedServices[T any](do.Injector) []do.EdgeService

type EdgeService struct {
	ScopeID   string
	ScopeName string
	Service   string
}

Service name​

Each service is identified in the DI container by a slug.

When using implicit naming, the do framework infers the service name from the type, by using the go-type-to-string library.

For debugging purposes, you might want to print the service name.

i := do.New()

do.Provide(i, func(i do.Injector) (*MyService, error) {
    return &MyService{}, nil
})

println(do.Name[*MyService](i))

Output:

// *github.com/samber/example.MyService

Provided services​

For debugging purposes, the list of services provided to the container can be printed:

i := do.New()

do.Provide(i, func(i do.Injector) (*MyService, error) {
    return &MyService{}, nil
})
do.ProvideNamed(i, "a-number", 42)

services := i.ListProvidedServices()
println(services)

Output:

[
   {ScopeID: "xxxxx", ScopeName: "[root]", Service: "*github.com/samber/example.MyService"},
   {ScopeID: "xxxxx", ScopeName: "[root]", Service: "a-number"}
]

Invoked services​

For debugging purposes, the list of invoked services can be printed:

i := do.New()

do.Provide(i, func(i do.Injector) (*MyService, error) {
    return &MyService{}, nil
})
do.ProvideNamed(i, "a-number", 42)

services := i.ListInvokedServices()
println(services)

Output:

[
   {ScopeID: "xxxxx", ScopeName: "[root]", Service: "a-number"}
]

In the example above, the lazy-loaded service *MyService has not been invoked.
